How do you know a dubbed video is good? I built an open-source tool to check
Description and use
<p>If you use AI dubbing, you've probably done this: a dub comes back, and the only way to know whether it's any good is to watch all of it. That works for one video. It stops working at twenty videos in five languages.</p> <p>So I built <a href="https://github.com/shox17/DubEval" rel="noopener noreferrer">DubEval</a>, a free, open-source desktop app that compares a dubbed video with its original and tells you whether the dub is ready to ship.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us
